请回应为您演示GLP-1 效用措施。GLP-1依照GLP-1R(1)后,GLP-1R在胰岛β癌人体细胞中偶联Gas球核蛋白,刺激启动腺苷环化酶(AC),促成cAMP在癌人体细胞内含量提高,可刺激启动球核蛋白激酶A(PKA)和cAMP调节器的鸟嘌呤核苷酸互换分子2(Epac-2)。After activation by full agonists such as GLP-1,GLP-1R(1) couples with Gas activates adenolate cyclase(AC),and causes the accumulation of cAMP.With increasing cAMP levels, protein kinase A(PKA) and the exchange protein directly activated by cAMP-2(Epac-2) are also activated.PKA 和 Epac-2 可不可以退出ATP依赖感关系症的钾阴化合物安全工作区,使细胞核膜去极化;还可不可以提高的电压依赖感关系症的钙阴化合物安全工作区(VDCC)使钙阴化合物内流并会产生运动电势,这一些渠道决定均会敏感血糖依赖感关系症性胰岛素的分泌量。PKA and Epac-2 trigger the closure of KATP and KV channels,which depolarizes the cell membrane opens voltage-dependent Calcium channels(VDCC) and causes Calcium influx and the promotion of insulin secretion by the islet beta cells
